我正在两台不同的机器上开发一个RoR应用程序。 iMac工作正常，所有Capistrano任务都按预期工作。但是，macbook-pro会为任何上限任务生成以下错误（甚至是“cap -T”）
luna:shootingstars sjf$ cap -T

尽我所知，两台机器上的设置都是一样的。我能找到的唯一区别就是在工作机器上......
sol:shootingstars sjf$ gem which bundler
/Users/sjf/.rvm/gems/ruby-1.9.3-p0/gems/bundler-1.0.21/lib/bundler.rb
在失败的机器上......
luna:shootingstars sjf$ gem which bundler
/Users/sjf/.rvm/gems/ruby-1.9.3-p0@global/gems/bundler-1.0.21/lib/bundler.rb
请注意ruby路径中的“@global”。
除此之外，两台机器都在运行
rvm version 1.10.2
ruby version 1.9.3p0
bundle version 1.0.21
capistrano version 2.9.0
rails version 3.2.1
感谢您的帮助

好吧，我终于找到了自己问题的答案。在文件系统中打开了“区分大小写”的问题，原来是Macbook Pro。 “Mac OS Extended（区分大小写，日记）”
从...更改deploy.rb文件行
require "Bundler/capistrano"
到
require "bundler/capistrano"
